Ruby 2.0.0-rc1 Tests

Quick test to compare Ruby 2.0.0-rc1 with 1.9.3p286.

I ran each command 5 times on each version. I'm using Seesaw's API in my tests.

Results

Ruby 2.0.0-rc1 is on average 15.778 seconds faster than Ruby 1.9.3p286 when running the Seesaw API Rails app test suite.

It's worth noting that no code changes were necessary to keep all of the tests passing.
